docker-packer-utils

Docker image with packer and other useful utilities

Why?

This image is used when following the 3 Musketeers pattern. By running packer inside Docker, we ensure consistency, control and confidence.

• Consistency: when developing automated processes that use packer, you can be sure that they will function the same whether you run it on your Windows workstation or on a Jenkins build agent.
• Control: by specifying the version of the image in [docker-compose.yml][], we can deploy to two incompatible versions of Packer simultaneously.
• Confidence: reliable deployments build confidence in the use of CI/CD pipelines, creating a positive feedback loop that encourages developers to use CI/CD

How To Use

deploy:
	docker-compose run --rm packer build
